黑龙江大麦调优栽培信息化技术研究进展

用卫星遥感技术准确的监控及地面SPAD值测定,结合专家系统,对大麦的长势、病虫害的发生和产量、品质状况进行诊断,再对大麦进行变量施肥、喷药等农业技术措施。该项技术主要环节在于卫星遥感图片所监视的影像数据、地面监测SPAD值与大麦生长健康程度的对应关系模型。该项技术的实施对于指导农户科学施肥,稳定大麦品质,提高产量,减少前茬药害、防止倒伏有着巨大的意义。

Research Evolution of Heilongjiang Barley Tuned Cultivation Technology

The use of satellite remote sensing and ground monitoring accurate determination of SPAD value,combined with expert system,the growing of barley,the incidence of pests and diseases,yield and quality are diagnosed,and then the barley variable fertilization spraying and other agricultural technical measures are carried out.Key link of this technology is that the monitoring of satellite remote sensing image data picture,correspondence relation model between the ground monitoring SPAD value and growth health of barley.The implementation of this technology is of great significance in guiding farmer＇s scientific fertilization,stabilizing barley quality,increasing production,reducing preceding phytotoxicity and preventing the lodging.
